'self-encourager' originates from the combination of 'self' and 'encourage', where 'self' refers to one's own person and 'encourage' means to give support or confidence.

'encourage' changed from the Old French word 'encoragier' and eventually became the modern English word 'encourage'.

Initially, 'encourage' meant 'to make strong or hearten', but over time it evolved into its current meaning of 'to give support or confidence'.
